Solutions
Check and replace the temp. sensor for
the upper tank water
Check and replace the temp. sensor for
the lower tank water
Check and replace the temp. sensor for
the evaporator inlet
Check and replace the temp. sensor for
the evaporator outlet
Check and replace the temp. sensor for
the Ambient
1. discharge the redundant gas
2. clean the air side heat exchanger
1.check if there is any leak and refill the gas
2.replace the filter or capillary
3.clean the water side exchanger or discharge
the air in the water loop
4.use new expansion valve
Check the water supply or tank whether
have enough water
Check the wire connection between
the wire controller and the main board
